Matroids of Gain Signed Graphs
Laura Anderson, Ting Su, Thomas Zaslavsky
A signed graph has edge signs. A gain graph has oriented edge gains drawn from a group. We define the combination of the two for the abelian case, in which each oriented edge of a…
Single-element extensions of matroids over skew tracts
Ting Su
Matroids over skew tracts provide an algebraic framework simultaneously generalizing the notions of linear subspaces, matroids, oriented matroids, phased matroids, and some other `…
Matroids over Skew Tracts
Ting Su
Matroids over tracts provide an algebraic framework simultaneously generalizing the notions of matroids, oriented matroids, and valuated matroids, presented by Baker and Bowler. Pe…
Classification of doubly distributive skew hyperfields and stringent hypergroups
Nathan Bowler, Ting Su
A hypergroup is stringent if is a singleton whenever . A hyperfield is stringent if the underlying additive hypergroup is. Every doubly distributive skew…
